Narrative:

Flight was vectored to final approach runway 14R at ZZZ. Runway 14R length is 13000 ft. The first officer landed on speed and centerline in the touchdown zone. He applied reverse while lowering the nose to the runway. When I said 'my aircraft,' control was xferred per aom vol 1. Within about 5 seconds from the completion of xfer, I heard a single chime and saw the EICAS message notifying me that the nose steering had failed. I tracked centerline with rudder and differential power while slowing the aircraft. As the speed slowed, the rudder became less effective and the aircraft started to drift left of the centerline by about 20 ft. At approximately 15 KTS, the aircraft suddenly turned more left. The nosewheel and left main departed the pavement onto the grass. The right main remained on the runway pavement. I notified the flight attendant and company and made a PA to the passenger explaining that we were slightly off the runway and that I had requested a bus to take them and their luggage into the terminal. Both flight attendants went with the passenger and the first officer and I remained with the aircraft for approximately 90 mins until we were transported by car to the chief pilot's office for drug testing. Callback conversation with reporter revealed the following information: the reporter stated there was no mechanical failure of the nose gear ground steering mechanism, only a movement of the steering tiller prior to the nose gear strut compression. The reporter said the xfer of control from the first officer to the captain must be accomplished with the nose strut compressed activating the nose gear steering. The reporter stated the first officer believed the nose strut was compressed and ground shift had occurred and xferred control. He said the steering tiller was moved and the nose steering disconnected as the nose strut was not fully compressed. The reporter stated the aircraft had no damage.

Title: A CRJ700 ON LNDG ROLLOUT EXPERIENCED A RWY EXCURSION DUE TO STEERING CTL LOSS. STEERING TILLER WAS MOVED PRIOR TO NOSE GEAR STRUT COMPRESSION.

Narrative: FLT WAS VECTORED TO FINAL APCH RWY 14R AT ZZZ. RWY 14R LENGTH IS 13000 FT. THE FO LANDED ON SPD AND CTRLINE IN THE TOUCHDOWN ZONE. HE APPLIED REVERSE WHILE LOWERING THE NOSE TO THE RWY. WHEN I SAID 'MY ACFT,' CTL WAS XFERRED PER AOM VOL 1. WITHIN ABOUT 5 SECONDS FROM THE COMPLETION OF XFER, I HEARD A SINGLE CHIME AND SAW THE EICAS MESSAGE NOTIFYING ME THAT THE NOSE STEERING HAD FAILED. I TRACKED CTRLINE WITH RUDDER AND DIFFERENTIAL PWR WHILE SLOWING THE ACFT. AS THE SPD SLOWED, THE RUDDER BECAME LESS EFFECTIVE AND THE ACFT STARTED TO DRIFT L OF THE CTRLINE BY ABOUT 20 FT. AT APPROX 15 KTS, THE ACFT SUDDENLY TURNED MORE L. THE NOSEWHEEL AND L MAIN DEPARTED THE PAVEMENT ONTO THE GRASS. THE R MAIN REMAINED ON THE RWY PAVEMENT. I NOTIFIED THE FLT ATTENDANT AND COMPANY AND MADE A PA TO THE PAX EXPLAINING THAT WE WERE SLIGHTLY OFF THE RWY AND THAT I HAD REQUESTED A BUS TO TAKE THEM AND THEIR LUGGAGE INTO THE TERMINAL. BOTH FLT ATTENDANTS WENT WITH THE PAX AND THE FO AND I REMAINED WITH THE ACFT FOR APPROX 90 MINS UNTIL WE WERE TRANSPORTED BY CAR TO THE CHIEF PLT'S OFFICE FOR DRUG TESTING. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THERE WAS NO MECHANICAL FAILURE OF THE NOSE GEAR GND STEERING MECHANISM, ONLY A MOVEMENT OF THE STEERING TILLER PRIOR TO THE NOSE GEAR STRUT COMPRESSION. THE RPTR SAID THE XFER OF CTL FROM THE FO TO THE CAPT MUST BE ACCOMPLISHED WITH THE NOSE STRUT COMPRESSED ACTIVATING THE NOSE GEAR STEERING. THE RPTR STATED THE FO BELIEVED THE NOSE STRUT WAS COMPRESSED AND GND SHIFT HAD OCCURRED AND XFERRED CTL. HE SAID THE STEERING TILLER WAS MOVED AND THE NOSE STEERING DISCONNECTED AS THE NOSE STRUT WAS NOT FULLY COMPRESSED. THE RPTR STATED THE ACFT HAD NO DAMAGE.
